My original assumption after looking at the pictures of the Conn DB referred to by Dave Werden above is that this is an HP horn converted to LP. The tuning slide in the leadpipe has the lengthened ferrules typical of a horn that is an HP convert.
Leadpipe tuning slides typically are much more sensitive than tuning slides after the valve section. An additional 1" of tubing near the leadpipe may have the same affect as 1.5" of tubing further on. In my experimentation with leadpipe length, I found a 1" extender at the receiver = 2x1" in ferrules at the tuning slide (i.e. 2" of tubing).
I would guess some judicious use of the 1-2-3 valve slides to get thyis horn to play in tune might be necessary, but it should be quite playable with the tuning slide it has.
